Abstract
Abstract An image reading apparatus comprising a photosensor for receiving light from a light source through an original document, a wiring section for driving the photosensor, a circuit for driving the photosensor and for processing an output signal from the photosensor. The apparatus includes a first substrate having the photosensor and the wiring section thereon, and a second substrate having the circuit thereon and being separated from the first substrate. The second substrate is fixed above the first substrate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
162 words
An image reading apparatus, comprising a photosensor for receiving light from an original document at a predetermined position relative to said photosensor, a wiring section for use in driving said photosensor, a circuit for driving said photosensor and for processing an output signal from said photosensor, a first substrate supporting said circuit, substrate means supporting said photosensor and said wiring section a base fixedly supporting said substrate means, a cap supporting said substrate at a position such that said substrate means is between said substrate and the predetermined position, and a flexible electrical connector electrically connecting said photosensor with said circuit; said cap, said base and said connector being so structured and arranged as to permit assembly of said apparatus by fixing said substrate to said cap, said substrate means and said connector to said photosensor and said circuit and thereafter putting said cap in place in contact with said base and fixing said cap and said base relative to each other.
